Hi,

I'm sorry, but I have a very limited knowledge of assembler. So I have no clue 
how to write something directly to the video memory or what registers I may or 
may not use. Can anyone give me some hints or send me some code fragments that 
I can insert into the track_int13 assembler function to see where it hangs?

Thanks, Volker
